For devotions in the Eastern Catholic Churches, refer to the articles on the individual Churches or the corresponding Orthodox Churches.
Roman Catholic devotions are "external practices of piety" which are not part of the official liturgy of the Catholic Church but are part of the popular spiritual practices of Catholics. Catholic devotions do not become part of liturgical worship, even if they are performed within a Catholic church, in a group, in the presence of a priest. The Congregation for Divine Worship at the Vatican publishes a Directory on Popular Piety and the Liturgy.
Devotion to saints, with the Virgin Mary as the most prominent example, is a key characteristic of Roman Catholicism. Catholic devotions have various forms, ranging from formalized, multi-day prayers such as novenas to activities which do not involve any prayers, such as Eucharistic adoration outside Mass, the wearing of scapulars, the veneration of the saints, and even horticultural practices such as maintaining a Mary garden.
Common examples of Catholic devotions include the Rosary, the Stations of the Cross, the Sacred Heart of Jesus, the Holy Face of Jesus, the various scapulars, the Immaculate Heart of Mary, Our Lady of Guadalupe, Seven Sorrows of Mary, novenas to various saints, pilgrimages and devotions to the Blessed Sacrament, and the veneration of saintly images such as among Santeros, etc.

There are many in the academic world of Catholicism and rank and file Clergy and laity that mock Popular Devotions and will not promote them in their parishes. One such example is the Divine Mercy Novena and Chaplet and the devotions associated with Divine Mercy Sunday.

Popular Devotions
Fr Joseph M Dias
Throughout its long history, the
faith of the Catholic Church has been nourished, not only by official
liturgical acts of worship, but also by innumerable Popular Devotions which it
has nurtured and encouraged. Undoubtedly, they are often highly impressive
public manifestations of the faith of the masses and are practised with great
zeal by millions of devotees in almost every Catholic home, parish, institution
and religious congregation.
